Spikelets with one perfect terminal fl, single or in clusters of 2 or 3 on unequal pedicels along one side of an elongate rachis, forming 2-several slender, spike-like racemes; first glume minute or lacking; second glume a third to fully as long as the spikelet, conspicuously 5- or 7-veined; sterile lemma (appearing as another glume when the first glume is obsolete) about as long as the fertile one; fertile lemma leathery with hyaline margins, acute, often shining, usually faintly marked with longitudinal rows of minute pits; palea flat, similar in texture to the fertile lemma, which clasps its margins; ours weedy annuals, branched from the base, with few-
several terminal, digitate or approximate, spike-like, one-sided racemes. (Syntherisma) 200+, cosmop.
